Extracts from 'Clinical Evidence': Pelvic inflammatory disease

摘要

Definition Pelvic inflammatory disease (PID) is inflammation and infection of the upper genital tract in women, typically involving the fallopian tubes, ovaries, and surrounding structures. Incidence/prevalence The exact incidence of PID is unknown because the disease cannot be diagnosed reliably from clinical symptoms and signs. Direct visualisation of the fallopian tubes by laparoscopy is the best single diagnostic test, but it is invasive and not used routinely in clinical practice. PID is the most common gynaecological reason for admission to hospital in the United States, accounting for 49 per 10 000 recorded hospital discharges. However, since most PID is asymptomatic, this figure almost certainly underestimates true prevalence.
